Description

Technical Field

[0001] The present invention relates to the technical field of battery recycling, and in particular to a method, a system and a storage medium for collecting waste power batteries. Background Art

[0002] With the large-scale retirement of new energy vehicles, the output of waste power batteries has been increasing year by year. Since waste power batteries contain a large amount of valuable metals such as lithium, cobalt, nickel, etc., their effective recycling not only helps the recycling of resources, alleviates the import pressure of strategic mineral resources, but also reduces environmental pollution and resource waste. However, at present, a large number of waste power batteries fail to flow into the formal recycling channels, which on the one hand leads to greater potential safety hazards in recycling, and on the other hand leads to low resource utilization rate and chaotic competition in the recycling market. Currently, there is a lack of an efficient and economic waste power battery recycling supervision system to promote the recycling of waste power batteries.

[0003] In addition, due to different usage scenarios and the diversity of battery structures and shapes, there are differences in the scrap utilization rate, safety and valuable metal content of different power batteries, which results in significant differences in processing costs from the collection to the pretreatment (waste power batteries become black powder) stage of waste power batteries, and also increases the complexity and difficulty of collecting and trading waste power batteries. At present, waste power batteries are often traded at a fixed price during the collection process, and the trading prices are diverse and deviate from the actual recycling value. The industry lacks an efficient, economic, open and fair collection and trading method. Summary of the Invention

[0068] As Figure 1 shown in the flowchart of the steps of a method for collecting waste power batteries provided by an embodiment of the present invention. Referring to Figure 1 , an embodiment of the present invention provides a method for collecting waste power batteries, which specifically includes the following steps:

[0069] S101. Obtain the target codes of multiple waste power batteries, and perform a matching query in a preset power battery database according to the target codes to obtain the target technical information of each waste power battery;

[0070] S102. Determine the cathode material type and rated capacity of each waste power battery according to the target technical information, classify each waste power battery according to the cathode material type, obtain multiple sets of batteries to be recycled, and count the total estimated capacity of each set of batteries to be recycled;

[0071] S103. Deliver the set of batteries to be recycled to a waste battery recycling enterprise for recycling treatment, so that the waste battery recycling enterprise returns recycled products of the same cathode material type and the same capacity or currency of the same value as the recycled products according to the cathode material type and the total estimated capacity of the set of batteries to be recycled;

[0072] Among them, the recycled product is one of a power battery and recycled materials. The recycled materials are recyclable materials obtained after recycling treatment of waste power batteries, mainly including metal elements (such as lithium, cobalt, nickel, manganese, etc.) and cathode materials (such as lithium iron phosphate, ternary materials, etc.).

[0073] Specifically, the recycling network obtains the battery code of the collected waste power batteries, which is the target code, and queries and obtains the corresponding technical information, which is the target technical information, according to the target code in the preset power battery database; determines the cathode material type and rated capacity of the waste power batteries according to the target technical information, and classifies the waste power batteries according to the cathode material type to obtain multiple sets of batteries to be recycled and calculates their total estimated capacity. It should be noted that each set of batteries to be recycled includes multiple waste power batteries of the same cathode material type, and its total estimated capacity is the sum of the estimated capacities of these waste power batteries.

[0074] The recycling network delivers the waste power batteries with a total estimated capacity of C to the waste battery recycling enterprise for recycling. The waste battery recycling enterprise delivers to the recycling network in one of the following ways:

[0075] 1) Deliver the recycled products with the same cathode material type as the waste power batteries in units of capacity, and deliver the recycled products with a total capacity of C. When the recycled product is a power battery, the total capacity of C means that the total rated capacity of the power battery is C; when the recycled product is recycled material, the total capacity of C means that the total capacity of the recycled material is C, and the total capacity of the recycled material = the mass specific capacity of the recycled material × the mass of the recycled material, or the total capacity of the recycled material = the volume specific capacity of the recycled material × the volume of the recycled material;

[0076] 2) Convert the recycled products with a total capacity of C in 1) into currency for delivery.

[0077] Specifically, when the recycling network is established for commercial users and the demand is for power batteries, the waste battery recycling enterprise delivers the factory power batteries with the same cathode material type and a total rated capacity of C as the above waste power batteries; when the recycling network is established for battery manufacturers and the demand is for recycled materials, the waste battery recycling enterprise delivers the recycled materials with the same cathode material type and a total capacity of C as the above waste power batteries; when the recycling network is established for third-party users, the waste battery recycling enterprise delivers the factory power batteries converted into currency according to the cathode material type and the total rated capacity C.

[0078] In the embodiments of the present invention, the waste power batteries are power battery monomers, modules, battery packs, etc. that are scrapped and lose their original use value during the processes of research and development, production, testing, storage, transportation, use, maintenance, vehicle scrapping, and cascade utilization; the recycling network is established by commercial users, battery manufacturers, or third-party users; the waste battery recycling enterprise includes recycling and regenerating the waste power batteries, and different regeneration products are obtained at different treatment stages. The regeneration products include recycled materials and power batteries.

[0079] In the embodiments of the present invention, the recycled waste power batteries are evaluated for recycling based on the estimated capacity of the batteries, which is applicable to waste power batteries of various types and application scenarios, simplifies the collection and trading processes of waste power batteries, improves the transparency and fairness of trading, facilitates the efficient trading of waste power batteries among battery manufacturers, commercial users, recycling outlets, and waste battery recycling enterprises, helps with the recycling and traceability of waste power batteries, prevents illegal dumping and environmental pollution, and improves the collection efficiency, resource utilization rate, and trading fairness of waste power batteries.

[0080] As Figure 2 shown is a flowchart of steps for constructing a power battery database provided by an embodiment of the present invention. Referring to Figure 2 , further as an optional implementation manner, the power battery database is constructed through the following steps:

[0081] S201. Code the factory-produced power batteries to obtain battery codes, and determine the battery technical information of each factory-produced power battery;

[0082] S202. Generate battery data key-value pairs based on the battery codes and battery technical information, and construct a power battery database according to the battery data key-value pairs;

[0083] Among them, the battery technical information includes the type of positive electrode material, rated capacity, nominal voltage, battery manufacturer, volume, mass, and specification code.

[0084] Specifically, the battery manufacturer codes the factory-produced power batteries and registers the battery technical information corresponding one-to-one with the battery codes. The technical information includes, but is not limited to, the type of positive electrode material, rated capacity, nominal voltage, battery manufacturer, volume, mass, and specification code, etc.; generate battery data key-value pairs based on the battery codes and battery technical information, and construct a power battery database based on the battery data key-value pairs of each factory-produced power battery, so as to directly query the database through the battery code to obtain the corresponding battery technical information when recycling waste power batteries.

[0085] As Figure 3 shown is a flowchart of steps for step S102 provided by an embodiment of the present invention. Referring to Figure 3 , further as an optional implementation manner, calculate the total estimated capacity of each set of batteries to be recycled, which specifically includes:

[0086] S1021. Obtain the current technical indicators of the waste power batteries;

[0087] S1022. Correct the rated capacity of the waste power batteries according to the current technical indicators to obtain the estimated capacity;

[0088] S1023. Statistically analyze the estimated capacities of used power batteries of the same cathode material type to obtain the total estimated capacity of the corresponding set of batteries to be recycled.

[0089] Among them, the current technical indicators include mass, volume, damage condition, deformation condition, leakage condition, and voltage.

[0090] Specifically, the rated capacity of the used power battery is corrected according to the current technical indicators of the used power battery to obtain the estimated capacity. The estimated capacities of the used power batteries of the same cathode material type are statistically analyzed to obtain the total estimated capacity of the corresponding set of batteries to be recycled. Among them, the current technical indicators refer to the technical indicators obtained by testing the used power battery, including but not limited to mass, volume, damage condition, deformation condition, leakage condition, voltage, etc.

[0091] As Figure 4 shown in the flowchart of a step of step S1022 provided by an embodiment of the present invention. Referring to Figure 4 , further as an optional implementation manner, the rated capacity of the used power battery is corrected according to the current technical indicators to obtain the estimated capacity, which specifically includes:

[0092] S10221. Determine multiple influencing factors associated with the estimated capacity of the used power battery by integrating market research, industry professional opinions, and research and analysis.

[0093] S10222. Determine the quantitative characterization data of each influencing factor of the used power battery according to the current technical indicators, and evaluate the quantitative characterization data of each influencing factor according to the actual recycling cost of the used power battery to obtain the cost influence value corresponding to the quantitative characterization data of each influencing factor.

[0094] S10223. Determine the weight factor of each influencing factor and determine the recycled product coefficient according to the type of recycled product.

[0095] S10224. Correct the rated capacity of the used power battery according to the cost influence value, weight factor, and recycled product coefficient to obtain the estimated capacity.

[0096] Specifically, through market research, industry professional opinions, and research and analysis, communicate and exchange with multiple used battery recycling enterprises, distribute questionnaires, and conduct online and offline interviews to conduct research and analysis on the energy consumption, time consumption, and safety in the recycling process of used power batteries, and obtain several influencing factors associated with the estimated capacity of the used power battery.

[0097] As Figure 5 shown in the flowchart of a step of step S10222 provided by an embodiment of the present invention. Referring to Figure 5, further as an optional implementation manner, evaluate the quantitative characterization data of each influencing factor according to the actual recycling cost of the waste power battery, and obtain the cost influence value corresponding to the quantitative characterization data of each influencing factor, which specifically includes:

[0098] S102221. Determine the cost reference level corresponding to each influencing factor according to the influence relationship between the quantitative characterization data of each influencing factor and the actual recycling cost;

[0099] S102222. Determine the cost level corresponding to each influencing factor according to the quantitative characterization data of each influencing factor and the preset grade evaluation standard;

[0100] S102223. Determine the cost influence value corresponding to the quantitative characterization data of each influencing factor according to the ratio of the cost level to the cost reference level.

[0101] Specifically, determine the quantitative characterization data of each influencing factor of different waste power batteries based on the current technical indicators obtained from the foregoing steps, evaluate and classify the quantitative characterization data of each influencing factor according to the actual recycling cost of each waste power battery, and obtain the corresponding relationship between the quantitative characterization data and the cost level X i and determine a certain grade as the cost reference level X according to the influence relationship (positive influence or negative influence) between the quantitative characterization data and the actual recycling cost i, , and determine the cost influence value corresponding to the quantitative characterization data of each influencing factor according to the ratio of the cost level to the cost reference level .

[0102] It should be noted that the influencing factors may specifically be multiple or all of the mass, volume, damage condition, deformation condition, leakage condition, voltage of the waste power battery. The mass and volume of the waste power battery will affect the disassembly and crushing efficiency; crushing, deformation, leakage and voltage will affect the safety during the disassembly and damage process. For example, if the waste power battery has large damage and deformation, it is more likely to cause explosion and fire, and requires specific sites for refined operation, resulting in a significant increase in the recycling cost.

[0103] The embodiment of the present invention determines the grade evaluation standard of each influencing factor by collecting quantitative characterization data of the influencing factors of a large number of waste power batteries and the corresponding recycling costs. Specifically, the quality, volume, damage, deformation and leakage of a large number of waste power batteries are collected for subsequent analysis, wherein the data of the quality and volume are the rated capacity mass density and the rated capacity volume density; the damage is divided into the damage area and the damage position, the data of the damage area is the percentage of the damage area to the total area of ​​the waste power battery, and the data of the damage position is the distance from the damage position to the risk position; the data of the deformation is the percentage of the deformation degree; the data of the leakage is the percentage of the area of ​​the leakage trace to the total area of ​​the waste power battery. The above-mentioned collected data of each situation are quantitatively labeled, and the quantitatively labeled data and the corresponding actual recycling cost are statistically classified by a machine learning algorithm, and the normalization process is performed to obtain the evaluation grade and corresponding cost level of the quality, volume, damage, deformation and leakage of the waste power battery, and the cost level is calculated to determine the cost reference level. In addition, the grade evaluation standard of voltage is obtained through expert scoring. The grade evaluation standards of various influencing factors obtained in the embodiment of the present invention are shown in Table 1 below.

[0104]

[0105] Table 1

[0106] The cost level is the level of impact that the influencing factors have on the cost at different quantitative levels. In the embodiment of the present invention, the cost level is 5, which has the greatest impact, and the cost of processing a unit capacity of waste power batteries in the battery recycling process is higher; the cost level is 1, which has the least impact, and the cost of processing a unit capacity of waste power batteries in the battery recycling process is lower. The cost reference level is a reference value, which is used as a benchmark to calculate the cost impact value of the influencing factors. 1 The absolute safety level voltage required by waste battery recycling companies, V 2 The recommended safe voltage level for waste power batteries during recycling and dismantling. The safe voltage level refers to the voltage range within which waste power batteries can be safely processed.

[0107] like Figure 6 FIG. 1 is a flow chart of step S10223 provided in an embodiment of the present invention, referring to FIG. Figure 6 As an optional implementation, the weight factors of the various influencing factors are determined, which specifically include:

[0108] S102231. Determine the subjective weight of each influencing factor through expert scoring method;

[0109] S102232. Determine the objective weight of each influencing factor based on the quantitative characterization data of each influencing factor by using the entropy weight method;

[0110] S102233. Weighted sum the subjective weight and the objective weight according to the preset adjustment parameter to obtain the weight factor of each influencing factor;

[0111] Among them, the sum of the weight factors of each influencing factor is 1.

[0112] Specifically, invite technical experts in the industry to determine the subjective weight K of each influencing factor through methods such as issuing questionnaires and using the scoring method 1 . The scoring can be carried out using a five-point system, a ten-point system or a hundred-point system. After scoring each influencing factor, perform normalization processing to obtain the subjective weight; use the entropy weight method to determine the objective weight K of each influencing factor 2 , so as to determine the weight factor K of each influencing factor K = λK 1 +(1 - λ)K 2 , where λ is the adjustment parameter, and its value range is [0,1]. The sum of the weight factors of each influencing factor is equal to 1. In addition, through real-time monitoring and feedback mechanism, the value of λ can be adjusted in a timely manner.

[0113] Further as an optional implementation method, the valuation capacity is calculated by the following formula:

[0114]

[0115] Among them, V represents the valuation capacity of the waste power battery, β represents the regeneration product coefficient, Z represents the rated capacity of the waste power battery, K i represents the weight factor of the i-th influencing factor, E i represents the cost influence value of the i-th influencing factor, and n represents the total number of influencing factors.

[0116] Specifically, collect the information of the waste power battery. According to the grade evaluation standard of the influencing factors, obtain the cost level of each influencing factor, and calculate the ratio of the cost level of the influencing factor to its cost reference level to obtain the cost influence value E of the influencing factor on the capacity of the waste power battery i , and then supplemented by the weight factor K i , to obtain the specific influence value K of the influencing factor on the capacity of the waste power battery i E i . Then, correct the rated capacity Z through the above formula to obtain the valuation capacity V of the waste power battery. It should be noted that β is the regeneration product coefficient, which is determined by the type of regeneration product delivered by the waste battery regeneration enterprise. The value of β is obtained through data analysis of factors such as the market price of the regeneration product obtained from the waste power battery at different treatment and recycling stages.

[0117] Such as Figure 7The following is a flowchart of the steps of step S1021 provided by an embodiment of the present invention. Refer to Figure 7 , and further as an optional implementation manner, obtain the current technical indicators of the waste power battery, which specifically include:

[0118] S10211. Obtain the image data of the waste power battery, perform feature extraction and feature discrimination analysis on the image data, and obtain the volume, damage condition, deformation condition, and leakage condition of the waste power battery;

[0119] S10212. Obtain the mass of the waste power battery by the standard weighing method;

[0120] S10213. Obtain the voltage of the waste power battery through an electrochemical detection system.

[0121] Specifically, by collecting the image data of the waste power battery, perform feature extraction and feature discrimination analysis on the collected image data through intelligent algorithms to obtain quantitative characterization data of volume, damage, deformation, and leakage. Among them, feature extraction includes ROI extraction and contour extraction, and feature discrimination includes contour fitting, color discrimination, and gray-level feature discrimination; obtain quantitative characterization data of the mass of the waste power battery by the standard weighing method; obtain quantitative characterization data of the voltage of the waste power battery through an electrochemical detection system.

[0122] It can be understood that the important application of waste power batteries is to extract and reuse the valuable metals contained therein. Therefore, the value of waste power batteries is mainly related to the types and contents of the valuable metals contained therein, and the rated capacity of the battery can more accurately reflect the content of the valuable metals contained therein. Therefore, through the type of the positive electrode material of the battery and the rated capacity, a collection method based on the rated capacity as the basis for trading can be obtained, and this method can be more accurate and closer to the recycling and trading value of waste power batteries. The recycling and trading value in the process of recycling waste power batteries is not only related to the rated capacity, but also related to the recycling cost in the process of treatment and regeneration and the category of the regenerated products. The recycling cost is also related to some physical and appearance factors of the waste power battery. Therefore, in the embodiment of the present invention, the rated capacity of the waste power battery is corrected by various factors, and the estimated capacity obtained reflects a more accurate trading value. Trading based on the estimated capacity can ensure the rationality and reliability of the transaction. At the same time, in the embodiment of the present invention, the estimated capacity of the waste power battery is used as the unit for trading among battery manufacturers, commercial users, recycling points, and waste battery recycling enterprises, which is beneficial to promoting the recycling and traceability of waste power batteries, and this method alleviates the storage pressure of the recycling points, and reduces the economic pressure of commercial users in purchasing power batteries. At the same time, using the battery estimated capacity as the unit for trading can simplify the trading process and improve the trading efficiency.

[0123] In the embodiments of the present invention, the recycled used power batteries are evaluated for recycling based on the estimated capacity of the batteries, which is applicable to used power batteries of various types and application scenarios, simplifies the collection and trading processes of used power batteries, improves the transparency and fairness of trading, facilitates the efficient trading of used power batteries among battery manufacturers, commercial users, recycling outlets and used battery recycling enterprises, helps with the recycling and traceability of used power batteries, prevents illegal dumping and environmental pollution, and improves the collection efficiency, resource utilization rate and trading fairness of used power batteries. In addition, in the embodiments of the present invention, the rated capacity of the used power batteries is corrected to obtain the estimated capacity for trading. The correction method takes the rated capacity of the used power batteries as the main body, comprehensively considers the recycled products obtained from the final treatment of the used power batteries and other influencing factors, rates the influencing degree of each influencing factor through the actual recycling cost to construct the evaluation criteria of the cost influence value, combines the expert scoring method and the entropy weight method to determine the weight of the cost influence value, and finally constructs a calculation model that takes the rated capacity of the used power batteries, the recycled product coefficient, the cost influence value of the influencing factors and the weight factor as inputs and outputs the estimated capacity of the used power batteries. The calculation process is efficient and accurate, further improving the collection efficiency, resource utilization rate and trading fairness of used power batteries.
